SHEET-METAL BAR FOR GLAZED STRUCTURES.

SPECIFICATION forming part of Letters Patent No. 437,129, dated September 23, 1890.

Application filed April 2,1890. Serial No. 346,299. (No model.)

.To all whom it may concern:

Be it known that I, WILLARD F. MILLS, of Kalamazoo, in the county of Kalamazoo and State of Michigan, have invented a new and useful Sheet-Metal Bar for Glazed Structures, of which the following is a full, clear, and exact description.

My invention relates to an improved metallic setting or glass-supporting bar, especially adapted to retain stained glass of different contours used in the production of ornamental artistic designs in windows or similar works of art, the object being to pro-' vide a light, strong, and handsome bar made out of sheetbrass or other metal in a manner that will be economical in cost of production and that may be formed to receive any ornamental configuration, whereby various designs can be produced in stained-glass work that will be neat in appearance as well as strong and water-tight in use.

To these ends my invention consists in certain features of construction and combinations of parts, as is hereinafter described, and indicated in the claims.

Reference is to be had to the accompanying drawings,forming a part of this specification, in which similar letters of reference in dicate corresponding parts in all the figures.

Figure 1 is a front elevation of a portion of a window embodying the improvement. Fig. 2 is a side view of an enlarged portion of a frame-bar and an attached re-enforcing bar. Fig. 3 represents an inside view of the reinforcing portion of an enlarged piece of the frame bent laterally. Fig. 4 is a transverse section of the frame portion shown in Fig. 2, taken on the line 4 4 in said figure. Fig. 5 represents the inner face of an enlarged piece of the frame bent to produce a circle at one end; and Fig. 6 is a cross-section of the framepiece shown in Fig. 5, taken on the line 6 6 in said figure.

The frame proper that is designed to retain pieces of glass by their insertion between flanges of the frame, which closely embrace the glass near their edges, is bent from a single straight strip of thin sheet-brass.

The portion A in Fig. 4. represents the framepiece after it is folded into form, and it will be seen to consist of an oppositely-channeled bar produoedby folding the material at a. 0/ upon itself so as to return the sheet toward a central point. At b b the sheet portions are bent at right angles to the flanges a a, thus affording a central web 0, and at d d the pieces composing the web are bent outwardly and oppositely, thus providing two flanges e e, which are parallel to the outer flanges a a.

The double channel-bars produced from thin sheet-brass, as stated, may by proper manipulation be bent edgewise, so as to permit curved as well as straight pieces to be provided, which can be arranged to conform to any ornamental design required, the variously-shaped bars being joined by soldering their ends or j unctional points, which when complete willbe ready to receive the glass that is cut-to suit the shapes provided in the frame.

In order to introduce the glass readily, the single flanges e e are bent down sufficiently, as shown in dotted lines in Fig. 6, these flanges being easily returned to place when the glass is seated in the grooves of the frame.

Where the window is exposed to violent storms, it is deemed advisable to insert a thin putty joint with the glass when setting it in the frame, which will seal all crevices and in time cement the whole structure, rendering the same strong and water-proof.

Where there is need for extra strength in the frame this is afforded by using the stifiening or re-enforcing bars B. (Shown in connection with the frame proper in Figs. 2, 3, and 4.)

A round, square, or flat bar of metal, preferably brass, or iron-wire rod that is tinned or coated with zinc by galvanizing the same is used to stiffen the frame-piece A, and in order to connect the bar and frame together the bar B is enveloped with a thin sheet of brass of such relative width that when bent around the rod or bar two parallel and adjoining flanges g g are produced, which are inserted between the webs c c and there secured by compressing the web 0 between any proper tool at intervals, so as to produce lateral indentations h, which will lock the re enforcing bar 13 fast to the frame-pieces A.

As the re-enforced bars B are only designed to stiffen a large window-frame at intervals throughout its surface, there may be straight portions of the frame produced in the design, as at '21 in Fig. 1, which will facilitate the introduction of the bars 13, that can be extended to form screw eye-holes on their ends, into which screws may be introduced and penetrate the wooden outer bars 0 of the window. It is apparent that the bars B may be also applied to curved frame-pieccs, as shown in Fig. 3, and these interspersed throughout the entire window-frame, if necessary, to impart rigidity to the multiform bars, or bars shaped in many ways to produce the desired design.

Havingthus described my invention, I claim as new and desire to secure by Letters Patcut- 1. In a metallic window-frame, the combination, with a series of multiform frame bars oppositely channeled and each bent from a single blank of sheet metal, of a series of reenforcing rods or bars that are enveloped with sheet metal and then attached to the assembled frame-bars, substantially as set forth. 2. In a structure of the character described, the bar or rod 13, having a sheet or strip of metal surrounding it, the longitudinal edges of the sheet or strip being formed into the attaching-flanges g, substantially as set forth. 3. The combination, with the channeled bar A, formed of sheet metal bent to form parallel flanges a Ct e e and spaced webs c, of the bar B, having a sheet-metal covering-strip, the longitudinal edges of which are bent to form flanges g to enter the space between the two webs a, substantially as set forth.
